Hello Mario,

since 02.09.2022 I no longer receive a notification for new posts. although I have entered the board "General Discussion and Questions" (see attachment).
That has also always worked. Last on 01.09.2022.
What can have happened there?

I think being able to temporarily adjust exposure would be useful while culling. I have a number of images where I have exposed for the sky meaning the foreground is in shadow and not possible to compare in imatch. Would be nice not to have to use other software for the comparison.
The actual database system should make no difference, all databases can export "CSV files" in one way or the other.
This is the route I would go if this is a one-time operation.

If this is a continuous process, writing a PowerShell, Python or other script which pulls the data out of the database system and then uses the built-in IMWS in IMatch to store the data into XMP fields is very doable. See for information about how other applications and programming languages can access IMatch database contents.
I'm guessing here - but at work we often refer to MDB as a Maria Database... just another relational database and a variation of MYSQL..

What's a MDB? Microsoft Access database?

PDF files support embedded XMP data, and IMatch does as well (read and write).
I would suggest you do this in two steps:

1. Export the data you want to use into a CSV text file (comma-separated values).
Export the fully-qualified file name in column 1:


2. Use the powerful CSV Import feature in IMatch to import the data from the CSV into XMP GPS lat/lon, title, headline, description, keywords...whatever data you keep in your database.

For GPS, import into XMP::exif\GPSLatitude\GPSLatitude and XMP::exif\GPSLongitude\GPSLongitude
See Tags and Groups and Metadata Tag ShortCodes if you are new to IMatch. Let us know when you need more info.

When IMatch writes back the metadata, it produces a standard-compliant XMP record and embeds it into the PDF file.
This makes the data accessible for all other XMP-compliant applications, including Adobe products like Acrobat Reader.

IMatch will use the coordinates to locate the PDF files on the map, you can perform reverse geocoding, display the coordinates in File Windows, edit them in the Metadata Panel etc.

Correct. But in this instance I guess the " File-Minimizer " software used was the culprit.

@LRAT: Be aware that the Forum software usually strips out all metadata. You need to zip images before you post them to guarantee they'll have all metadata.

I have thousands of PDF files created from scans with no meaningful embedded metadata, but have a script to generate tags and records in an MDB with lat/lon coordinates. Is it possible to push file-embedded metadata from an MDB to the IMatch DB by filename?

This image has no metadata at all, sorry.
You can send the original file to my support email, see support email address.

I have looked into this and this will require substantial work. The flow of the slide show makes it predictable which images come next, which allows to prepare and transform the images for the blend effects on the GPU.
Allowing the user to navigate to random slides while keeping the transitions working will be doable but also require quite some changes in how the slide show works, how it prefetches images, how it does transitions etc.

Since the slide show is one of the least used features in IMatch according to telemetry, I won't put any additional effort into this unless a sufficient number of users considers this to be something they want. The slide show feature is basically unchanged since IMatch 5 back in the day. As always, if enough users +1 the request, I will happily look into it.

Please file a feature request in the official board so we can learn how many users would like to have this.

As you said, there are plenty other slide show tools around you can use if you are not satisfied with how IMatch implements manual navigation in the slide show in combination with transitions.
